Hi all,
in case of using 5S configuration and External balancing, is this circuitry needed?

or is it only a driver for the 7th cell case it is installed?

is this the correct way to connect sense and Ext. balancing to the BQ40Z80 for 5S ?
thanks
Ran

Hello Ran,
Your second image is correct for 5S configuration from what I can see. The extra FET is for 7S support.
